Lab: exercise and homeostasis lab report
if anyone has done this pls help
ill give brainliest
Introduction:
The question that was trying to be answered in this lab was “How does exercise affect a person’s heart rate, breathing rate, and perspiration level?” Based on this question, the hypothesis that was formed was “If effects of exercise and exercise are related, then exercising will increase heart rate, breathing rate, and perspiration level”.
What is homeostasis?Homeostasis refers to the mechanism of the body to maintain a stable internal environment instead of changes taking place in the external environment.
Homeostasis in the body is maintained through three vital organs, as mentioned before, the kidneys, liver, and brain. These regulate the temperature, iron content in our blood, retention, and production of energy and overall blood composition. This was helpful because the whole lab report was based on homeostasis and the effect that it had on exercise.
Materials and Methods:
1. Materials:
a. People to exercise
b. A clock or stop watch
2. Procedure:
Choose one volunteer to complete jumping jacks at a pace that can be maintained for eight minutes. Make sure the volunteer is inactive for a few minutes before the experiment begins.Measure the heart rate by taking his or her pulse, you can do this one of two ways: Radial Pulse, Carotid PulseMultiply the number of beats in 15 seconds by 4 to calculate the beats per minute. Record the data in the table below the 0 minutes box.Measure the person’s perspiration level from 0 to 5: (0 = none; 5 = droplets dripping down the face). Note this observation in the table. Have the volunteer do jumping jacks for 2 minutes. After 2 minutes, measure the heart rate, breathing rate, and perspiration level (refer to steps 2 through 5), and record the data. Measure the pulse, breathing and perspiration levels as quickly as you can so that the volunteer can resume exercise. Do not have volunteer wait while you do the calculations and enter the data. Repeat step 6 three more times (remember, 2 minutes each at a time, totaling 8 minutes) and record your data at each point. After the final recording of the dependent variables, wait one minute with the volunteer at reset. Then measure all of the variables again. Record this data under the “9 Time (Min.) Box”.Analysis:
There is an increase effect of exercise over time on the circulatory and respiratory systems, as shown in both Table 1 and Table 2. As the students began their exercise in two-minute intervals, their heart rates increased on average from 73 beats per minute to 115 beats per minute. Shawn’s individual heart rate began at 84 beats per minute, and after lifting 5-pound weights for 8 minutes, his heart rate increased to 114 beats per minute . Also, his breathing rate showed an increase from 36 breaths per minute to 44 breaths per minute.
Based on this data shown, the amount that you exercise does effect the circulatory and respiratory systems by causing a, on average, dramatic increase in beats/breath per minute in the measured variables.
Conclusion:
According to the data collected, the hypothesis that was developed at the beginning of the experiment: “If effects of exercise and exercise are related, then exercising will increase heart rate, breathing rate, and perspiration levels”; was accepted . Based on the data shown our individual group charts and the class averages, the effect that exercise has on the respiratory and circulatory systems is that it develops an increase in heart rate (Start: 73/ Finish: 115), breathing rate (Start: 38/ Finish: 56), and perspiration levels (Start: 0/ Finish: 1).

What process governs the function of the respiratory surface?
"Now, gas exchange in the lungs refers to the movement of oxygen into the blood and carbon dioxide out of the blood. Oxygen and carbon dioxide move across what we call the respiratory surface, and that consists of an alveolar epithelial cell and a pulmonary capillary endothelial cell"

You are studying the phenotypic traits of bone density and muscle mass in cattle and find that the two traits have a correlation coefficient of -1.0. What is the interpretation of this statistic
A correlation coefficient of -1 means that bone density and muscle mass are perfectly correlated but in opposite ways.
Correlation coefficientThe correlation coefficient, r, is a measure of the strength of the relationship between two variables.
r = 0 means that the two variables in question have no relationship, r = 1 means that the two variables are perfectly correlated in the same way, and r = -1 means that the two variables are perfectly correlated but in opposing ways.
The implication of the -1 correlation coefficient is that bone density increases with decreasing muscle mass and vice versa.
